With the development of smart lighting devices, more and more people are purchasing smart lighting devices from various sources. Most of the products are noted as "smart" control lighting equipment, but how is smart control achieved?
In fact, intelligent control methods include Bluetooth, Bluetooth mesh, WIFI, and Zigbee, the most common is Bluetooth and WIFI, this article will tell you the difference between them!
The difference between Bluetooth and WiFi
Different working methods
The full name of WiFi is WirelessFidelity, also known as 802.11b standard. Commonly known as wireless broadband, it belongs to WLAN wireless local area network and supports the network mode of multiple terminal devices transmitting at the same time, i.e. the one-to-many mode. It has a transmission range of 100m, can reach a maximum speed of 11Mbps, uses DSSS (Direct Sequence Spread Spectrum) and QPSK or BPSK (Phase Shift Keying), and has an upper and lower bandwidth of 22MHz.
Bluetooth is part of the WPAN wireless personal area network, i.e. point-to-point, multipoint-to-multipoint, and is mainly used to connect external devices or to transfer data in close proximity. For example, Bluetooth headsets, mobile phones and tablets can be used to transfer files.
The bluetooth transmission bandwidth is 1Mbps, communication distance is about 10m (in April this year, the latest version of Bluetooth 4.0 can reach 50m), using the FHSS (Frequency Hopping Spread Spectrum) method, generally 1600 times per second, the 83.5MHz frequency band is divided into 79 channels, each moment only occupies 1MHz of bandwidth The modulation method is GFSK (Gaussian Frequency Shift Keying).
WIFI connection to the network is generally password-protected, but also easy to be cracked through technical means, so the security is relatively low.
And Bluetooth breaks the limitations of the wired cable to connect various digital devices, wireless communication quality is good, data security performance is high.
Different application sites
One of the biggest advantages of WIFI is its fast transmission speed and the fact that it does not require wiring, in fact it converts wired network signals into wireless signals that can be connected to all devices that need wireless internet access, such as smartphones, tablets and laptops, etc. WIFI is more suitable for indoor scenarios, especially in corporate and home environments, as it can directly connect various electronic devices to the network for a variety of interactions.
Bluetooth, on the other hand, can be used for both data and voice communication wirelessly, playing the role of a connection, and can be integrated into a wide range of digital products such as mobile phones, headphones, printers, keyboards, lighting fixtures, cameras and so on. These digital products are suitable for outdoor scenarios due to the factory-installed Bluetooth module and the high security and low power consumption.
Different frequencies of quartz crystals
Quartz crystals are used to generate the frequencies that control and manage all communication systems and are an essential component in most clocks, watches, computers and microprocessors and are an integral part of modern electronics. Quartz crystals play an important role in two wireless technologies, Bluetooth and WIFI.
In Bluetooth technology products, the commonly used quartz crystal frequencies are 12.000 MHZ, 16.000 MHZ, 24.000 MHZ, 26.000 MHZ, 32.000 MHZ, etc.
In WIFI technology products, the commonly used quartz crystal frequencies are 20.000 MHZ, 40.000 MHZ, etc.
Wi-Fi is better than Bluetooth in terms of ease of networking, transmission rate and distance, while Bluetooth is better than Wi-Fi in terms of data stability, security and ease of networking; users can choose according to their needs.
